14、nse, France ANSI X3.53- 1976 American National Standard Programming Language PWI Secretariat Computer and Business Equipment Manufacturers Association Approved August 9, 1976 American National Standards Institute, Inc Abstract This document defines American National Standard Programming Language PL/
15、I and specifies both the form and interpretation of computer programs written in PL/I. The standard is intended to provide a high degree of machine independence and thereby facilitate program exchange among a variety of computing systems. The document serves as an authoritative reference rather than
16、 as a tutorial exposition. The language is defined by specifying a conceptual PL/I machine which translates and interprets intended PL/I programs. The relationship between an actual implementa- tion of PLA and the conceptual machine presented in this document is also given. This reference document w
17、as developed jointly under the auspices of the American National Standards Institute and the European Computer Manufacturers Association. Indexing terms: PL/I, computer programming language, computer programming language def- inition, formal languages. AmericanNationalStandardApproval of an American
18、 National Standard requires review by ANSI that therequirements for due process, consensus, and other criteria for approval havebeen met by the standards developer.Consensus is established when, in the judgment of the ANSI Board of StandardsReview, substantial agreement has been reached by directly
19、and materiallyaffected interests. Substantial agreement means much more than a simplemajority, but not necessarily unanimity. Consensus requires that all views andobjections be considered, and that a concerted effort be made toward theirresolution.The use of American National Standards is completely
20、 voluntary; their existencedoes not in any respect preclude anyone, whether he has approved the standardsor not, from manufacturing, marketing, purchasing, or using products, processes,or procedures not conforming to the standards.The American National Standards Institute does not develop standards
21、and will inno circumstances give an interpretation of any American National Standard.Moreover, no person shall have the right or authority to issue an interpretation ofan American National Standard in the name of the American National StandardsInstitute. Requests for interpretations should be addres
22、sed to the secretariat orsponsor whose name appears on the title page of this standard.CAUTION NOTICE: This American National Standard may be revised orwithdrawn at any time. The procedures of the American National StandardsInstitute require that action be taken periodically to reaffirm, revise, or

25、d is not a part of American National Standard Programming Language PL/I, X3.53-1976.) In October 1963, a committee was formed by the SHARE FORTRAN Project and the Intema- tional Business Machines Corporation to extend FORTRAN, then the primary high-level language used by scientific programmers. The
26、extended language was to be suitable for commercial and systems programs as well and was to take into account the architecture of modern computers. The committee soon determined that the language would have to differ from FORTRAN, and their report, presented in April 1964, was entitled “Specificatio
27、ns for the New Programming Language.” The New Programming Language was widely discussed. Revised descriptions were issued, and in 1965 it was renamed PL/I (for programming language one). Versions were implemented on the computers of at least two manufacturers by late 1966. By April 1966, Technical C
28、ommittee 10 (TC 10) had been set up by the European Computer Manufacturers Association (ECMA) and an ad hoc group by American National Standards Com- mittee X3 to investigate the development of PL/I standards. TC 10 embarked immediately on standardization but the Standards Institute group considered
29、 first whether PL/I was a suitable candidate. Early in 1969 Technical Committee X351 was formed by American National Stan- dards Committee X3 to carry out the work in conjunction with TC 10. The two technical committees, X3Jl and TC 10, formed the joint PL/I standardization project. Building on the
30、work begun by TC 10, nearly 3500 proposals for language or textual change were processed in developing a joint draft standard for PL/I. The joint working document under- went thirteen complete revisions. During this time, the definition evolved from an imprecise English description to a precise spec
31、ification in a semiformal metalanguage using a stylized English. The Joint Project has enjoyed excellent liaison with potential users and with other standards organizations such as International Organization for Standardization Technical Committee 97, Subcommittee 5 (ISO/TC 97/SC 5) and PL/I working
32、 groups in Austria, France, Germany, the Netherlands, Japan, and the United Kingdom. Suggestions for improvement of this standard will be welcome. They should be sent to the American National Standards Institute, 1430 Broadway, New York, N.Y. 10018. This standard was processed and approved for submi
33、ttal to ANSI by American National Stan- dards Committee on Computers and Information Processing, X3. Committee approval of the standard does not necessarily imply that all committee members voted for its approval. At the time it approved this standard, the X3 Committee had the following members: J.
